Introduction
Did you buy a new phone recently with a massive 5000mAh battery, promising two-day battery life, but it still dies by 5 PM?
Itโs incredibly frustrating. You paid good money, and now you are stuck carrying a power bank everywhere. But before you blame the phone manufacturer or think your battery is defective, listen to this:
As GadgetGyaniโs Android Expert, I can tell you that in 90% of cases, the problem isn’t the physical battery. The real culprits are unoptimized apps, the constant hunt for weak 5G signals, and hidden settings that suck power in the background without you knowing.
You don’t need a new phone; you need better settings. By tweaking just 7 simple things listed below, you can easily boost your battery life by 20-30% today. Let’s fix this.
7 Settings to Change to Stop Battery Drain
1. The “5G Factor”: Switch to 4G for Daily Use
In 2025, 5G is everywhere in India, which is great for speed, but terrible for battery life. 5G modems consume significantly more power than 4G.
If you are in an area with patchy 5G coverage, your phone constantly works overtime switching between 5G and 4G towers. This modem activity drains the battery rapidly and causes heating.
- The Fix: Unless you are downloading a huge movie file, 4G LTE is fast enough for Instagram, WhatsApp, and YouTube.
- How to change: Go to Settings > Network & Internet > SIMs > Preferred Network Type and select LTE/4G.
2. Manage Screen Refresh Rate (120Hz vs. 60Hz)
Most modern mid-range phones come with smooth 120Hz displays. While it looks fantastic, rendering 120 frames every second puts a heavy load on the battery.
- The Fix: You don’t need 120Hz just to read emails. If your phone has an “Auto” or “Adaptive” option, use that. If battery life is your top priority, switch back to standard 60Hz.
- How to change: Go to Settings > Display > Motion Smoothness (or Refresh Rate) and select Standard or Auto-switch.
3. Dark Mode is Your Best Friend (For AMOLED Screens)
If your phone has an AMOLED display (most Samsung, Xiaomi, Realme phones over โน15k do), Dark Mode is a lifesaver.
On an AMOLED screen, black pixels are actually turned off. White pixels require the most power. Using Dark Mode means a huge portion of your screen isn’t using any battery at all.
- How to change: Go to Settings > Display and turn on Dark Mode. You can also schedule it to turn on automatically at sunset.
4. Put Rogue Apps to “Deep Sleep”
Why is the Shopping App you used once last week still running in the background checking for location? Many apps run unnecessary processes that keep your phone “awake” even when the screen is off.
- The Fix: Android has a built-in feature to stop this.
- How to change: Go to Settings > Battery (or Device Care) > Background Usage Limits. Add apps you rarely use to the “Deep Sleeping Apps” list. They won’t run until you open them again.

5. The Hidden Drainer: Wi-Fi & Bluetooth Scanning
This is a sneaky one. Even if you turn off your main GPS and Wi-Fi toggles from the notification shade, your phone might still be scanning for nearby Wi-Fi networks and Bluetooth devices in the background to improve location accuracy.
- The Fix: Turn off these hidden scanners.
- How to change: Go to Settings > Location > Location Services. Find Wi-Fi Scanning and Bluetooth Scanning and turn them OFF.
6. Turn Off Haptics (Vibration)
Does your phone vibrate every single time you tap a letter on the keyboard? That feels nice, but it means a tiny physical motor inside your phone has to spin up hundreds of times a day. This mechanical action eats battery.
- How to change: Go to Settings > Sound & Vibration > System vibration. Turn off Keyboard vibration and Touch interactions.
7. Remove the Bloatware
New phones in India often come loaded with “junk” apps (bloatware) pre-installed by the brand or carrier. These apps take up storage and often run annoying notifications or background processes.
- The Fix: Be ruthless. If you don’t use an app, get rid of it.
- How to change: Long-press the unwanted app icon and tap Uninstall. If you can’t uninstall it, tap Disable.
Bonus Myth Buster! ๐ง
“Does closing apps from the ‘Recent Apps’ menu save battery?”
Answer: NO.
This is the biggest myth in Android. Modern Android is very smart at managing RAM. When you force-close an app, the phone has to use more CPU power and battery to re-launch it from scratch the next time you need it. Stop swiping them away; let Android do its job.
Conclusion
You usually don’t need a new phone just because the battery is draining fast; you just need to stop your current phone from working too hard unnecessarily. Try these 7 settings for a week, and you will definitely see a major improvement in your screen-on time (SOT).
However, if your phone is more than 3-4 years old, heats up constantly even while doing nothing, and the battery health is physically degraded, it might be time for an upgrade. Check out our guide on the [Best 5G Phone Under 20000] for great budget-friendly options.
